This game has so much depth, from the very start you can personalise your character with race, class and birthsign, of which there are endless choices, from combat to magic, and stealth to acrobatics. There is a long and gripping main quest, and thousands of small side quests for special weapons, guilds etc. Graphics are jaw-dropping, and not too demanding on your PC, make sure you have a 2.0 Ghz processor though. There are endless opportunities to improve your character, and an advanced levelling system. The free roam capability means you can go anywhere you want. Anywhere. Mods are available online from various websites, and you can create your own armour etc. The expansion packs are extremely worthwhile, make sure you get your hands on them too, I advise the game of the year edition.
